Do I have any chance to get a postdoctoral position in quantum gravity?

Hi all,

I'm a Chinese doctoral student, who will graduate the next year if no
incident occurs. My major is astrophysics, and two and a half years
ago, I got my Master degree in atomic physics. These two subjects are
about tiny objects and huge objects respectively. Now I want to have
some understanding on the quantum gravity, since this theory may solve
the divergence of quantum mechanics and the general theory of
relativity.

However, it seems very difficult to get a postdoctoral position on a
different Major. Anyone could give me some suggestions? (My CV and
Major are listed on the website:
http://astronomy.nju.edu.cn/~zouyc/index_en.html)

Any comments are appreciated.
